Simple question, can I change my nickname? I haven't used this one for ages anywhere else on the internet.

It's common practice on other boards I know, although usually limited to avoid people wanting to change their nicknames every other week. But I've never seen it even discussed here.

Yes, a change of nickname is possible. However, it is not a 'self-help' process. Send a PM to any of the Admin members, for instance, Gilles4Ever, Pascal or mel and they will effect a change for you. Be warned though, this is a one time only request.
